The γ-aminopropyltriethoxy糖心产精国品免费入口*完整版 was deposited on 6061 aluminium alloy surface. The 糖心产精国品免费入口*完整版of the 糖心产精国品免费入口*完整版 was investigated in 3.5% NaCl solution, using Tafel 糖心产精国品免费入口*完整版s. The results showed that silane solution was stable when the silane concentration was 3%, pH value was 12 and time of hydrolysis was 72 h at room temperature. When aluminum alloy specimen in silane solution was treated by dip-coating 3 min, curing temperature 180 ℃ and curing time 120 min. the obtained 糖心产精国品免费入口*完整版s on 6061 aluminium alloy surface had the best corrosion resistance, the corrosion current density reduced and corrosion potential rose.
